The bottom of each tailin'gs compartment 16 is provided'with an outlet spout 25 through which the :tailings are discharged into receivers 26 having spouts 27. The bottom of each cell is also provided with a valved spout 28 whereby the contents of the-cell may be withdrawn. 1

For the purpose of discharging mixed ore and water into the several cells of the'concentrator, I provide a main chute-29 and provide at intervals hoppers 30-.i1ito which the main chute dis harges, having a lateral chute 31 extending therefrom and forwardly and rearwardlyextending chutes 32 which discharge into lateral chutes 33 by means of hoppers 34. The hoppers 30 and the hoppers 34 are provided with waste pipes 35. Each of these lateral chutes discharge into a corresponding feed box 11 at the end thereof opposite the partition 21.

In actual practice the feed boxes are about 9 feet long, 12 inches wide, and a space of about 12 inches is left from the bottom of,v

the feed box to the top of the screen to provide a space for the chats separator vand the passage of the tailings over the top of the separator. The concentrator is to be constructed in any usual; or suitable manner and any number of cells may be, arranged n a battery, I a

I am aware that it is common in concentrating jigs to use a plurality of cells each provided with a grating and to feed the material successively from one cell to a succeedmg cell of the series. In other Words, the materlal 1s passedover a series of grates and waste material is passed from cell to cell. In these jigs the pulp or other material isiall dumped onto the head cell of the series and thereafter passed to each succeeding cell in the series, thereby causing each cell in the series to handle all the waste material that is dumped onto the first cell. In my construction, the contents of the elevatorv is divided between a plurality ofcells as, for instance, six cells and the waste material isv taken up ifrom each. cell, thereby saving the handling of this waste material live times trator, the greater part of the metal is re tained on' the grate, of the first cell to form the bed thereof, thereby reducing the metal 60' which passes over :to'the next succeeding cell thereby reducing thev'metal-bed in each succeeding cell and at-the same timeireduc- -ing thecleaning efiiciency of each succeeding cell, until finally the last cells] inthe series are practically functionless and hanover and the crowding .ofany one,

concentrate ore by dle practically nothing but waste material which has been discharged from the preceding cells. In my type, of concentrating jig as heretofore described, each cell performsthe same function and by reason of the fact that the contents of the elevator is discharged onto and'divided between the six cells instead'of one, overloading andf overcrowdlng is done away w1th and each cell is given a uniform metal bed of its own and is thus enabled totake out practically the entire metal contents of the material.

A further advantage of a concentrator arranged in accordance with this invention over the ordinary concentrator ofthe same type, lies in the uniform distributionof water to each cell. In the ordinary type of concentrator operating on this principle, the' entire water contents used in cleaning the ore is discharged int'othe first cell and increasesin volume as it is passed on to each succeeding cell until at the last cell there is six times as .much water as is necessary to properly operate the cell and by reason of this excess vwater a large amount oflthe very fine ore is carried oil with this excess water into the tailingspile. In my im proved concentrator. the water. like the" ore, is dis hargedequallyto each of a plurality of cells and ea h cell discharges its own waste material with its own water and thus;

the fine ore that is carried away with the excess water inthe ordinary concentrator of this type is saved in a concentrator constructed in accordance with thisinvention',

thereby causing a very large saving of this fine ore. a 7

While I have illustrated a specific embodiment of'my improved con entrator. it;

is to be understood that various" changes maybe made in the details ofconstruction and arrangement of the parts without departin from the spirit of the invention.

1. A concentrator including two cells,

there being a wall between the ,adiacent ends of the cells and extending up the full hei ht of the cells and separating them en tirelvffrom each other. a tailings box disposed against said wall at the discharge end i of one cell" and opening'at its upper end into 931d cell, a feed box disposed immediatelv above the tailins 'sxbox above the opening into'the cell. the bottom'of the feed boxforming the top of the tailings box and discharging onto the receiving end of the next cell. and means for discharging ore and water into thejeed box.

' A concentrating ig-comprising a plurallty of independent cells. each' cell having a grate. means for causin the interroittent sur ing of water throu h the grate,

each cell having at one end a'feed box disposed ona levelhigher thanthe grate and discharging thereon,'each cell at its opposite end having chats separator, and a tailings box, the body of the cell and the tailings box having dischar e spouts, and means for conveying material directly to each feed box, each feed box being provided adjacent one end with an upwardly extending partition less in height than the height of the feed box and providing means for withdrawing surplus water from the feed box.

3., A concentrating jig com rising two I cells, each cell havin a grate, t e discharge 7' end of each cell having a tailings box, into 1 which the tailings from the corresponding grate discharges and each cell above the tailings box being formed to provide a feed box having spouts dischargin onto the next adjacent grate and provide with means for withdrawing surplus water, each cell having means for causing the intermittent surging of water upward through the grate and having means forwithdrawing material from the cell and from the tailings box,

and means for discharging pulp independently into each feed box.
